Beschreibung:
Author(s): Jing-Min Hou and Wei Chen We propose a scheme to realize a Z 2 topological insulator in a square optical lattice. Different from the conventional topological insulator protected by the time-reversal symmetry, here the optical lattice possesses a hidden symmetry, which is responsible for the present Z 2 topological order. With … [Phys. Rev. A 93, 063626] Published Mon Jun 20, 2016
